Objecting to a ZATCA Assessment: The Deadline, the Items and Building the File

Receiving an assessment notice from the Zakat, Tax and Customs Authority (ZATCA) for an amount exceeding what the business declared is not the end of the road. The taxpayer has a right of objection, that right has a defined period, and allowing it to lapse makes the assessment final — regardless of whether it was correct.

This area is dominated by material written from a legal perspective, yet a successful objection is, in most cases, not a legal argument but an accounting file: a document that substantiates an item, a reconciliation that explains a difference, a correct measurement basis replacing an estimate. The law opens the door; the accounting wins the room.

When does an assessment become final?

Article 117 of the Implementing Regulations for Zakat Collection provides that an assessment becomes final in two cases: on the expiry of sixty days without an objection being filed, or on a decision of the dispute resolution committees rejecting the objection.

The practical consequence is that the period is short relative to the time required to assemble a coherent objection file. The first decision on receiving a notice is therefore not “should we object?” but “what documents do we need and are they available?” — because the second answer determines the first.

Which regulations apply

Before arguing any item, establish which regulations govern the year under assessment. The Implementing Regulations for Zakat Collection, version 1445H, issued by Minister of Finance Decision No. 1007 dated 19/8/1445H, apply to financial years beginning on or after 1 January 2024, and superseded all preceding decisions, instructions and circulars on zakat collection.

Citing a provision from an earlier set of regulations for a year governed by the 1445H regulations — or the reverse — is among the most common ways an objection is weakened on form before it is even considered on substance.

The assessment items most open to objection

In practice, the points of dispute recur in the following areas:

Point of dispute	The substance	What usually settles it
Deductions from the zakat base	The Authority disallowing a deduction claimed — such as net fixed assets, intangibles or investments	Establishing the nature and classification of the asset and linking it to the provision governing the deduction
Additions to the base	Amounts added that the taxpayer considers should not be — certain provisions or credit balances	Analysing the nature of the balance, when it arose, and its supporting documents
Deemed base	The Authority resorting to estimation because books or documents were insufficient	Producing books and documents sufficient to move the case from estimation to actual computation
Minimum and maximum base	Misapplication of the minimum or maximum base rules	Recomputation under the articles governing them
Differences between statements and return	Return figures diverging from the filed financial statements	A reconciliation schedule explaining every difference by item and document
Withholding tax	Dispute over the characterisation of payments to non-residents and the rate applied	The contracts and what the service actually was, rather than how the invoice described it
Value added tax	Input tax deduction or the treatment of a supply in dispute	Completeness of the tax invoice conditions and evidence that inputs relate to the activity

What makes an objection strong?

1. Item by item. A general objection to the total is weak by nature. A strong objection addresses each item separately, stating the amount objected to, the ground, the supporting document, and the numerical effect on the base.
2. Anchored to the governing provision. Each item has a basis in the regulations applicable to the year under assessment, cited precisely.
3. A complete recomputation schedule moving from the base assessed by the Authority to the base the taxpayer considers correct, item by item, so the whole difference can be traced.
4. Numbered and cross-referenced documents. Every figure in the schedule has a reference in the document bundle.
5. Consistency with what was previously filed. An objection that contradicts the return or the filed financial statements undermines the taxpayer’s whole position, not merely the disputed item.
6. Realism in choosing the battles. Including weak items alongside strong ones weakens the file. Professional selection is part of the preparation.

The statutory route

An objection is filed in the first instance with the Authority through its electronic services. Where it is not accepted, litigation in zakat and tax disputes proceeds before the committees for resolution of tax violations and disputes, whose work is organised by the General Secretariat of Tax Committees, with an appeal tier.

Because the filing and appeal deadlines before these committees are precise and bear on the forfeiture of rights, the sounder course is to verify them from the official source in each case, and to take legal advice alongside the accounting preparation of the file.

A decision that precedes the objection: penalties or principal?

There is a practical consideration that many overlook in 2026 specifically. The fines cancellation initiative running to 31 December 2026 requires, as a condition of benefiting, payment of the full principal debt.

A business with a disputed assessment therefore faces a real trade-off:

• Settle and obtain the penalty waiver — securing a certain saving, but requiring payment of a principal that may be disputed.
• Pursue the objection — which may reduce the principal, but consumes time during which the initiative window may close.

The trade-off is quantitative: the probability of success and the expected reduction, against the penalty amount that can be waived with certainty. It is assessed case by case and does not lend itself to a general rule.

Prevention: what reduces the likelihood of an assessment

• Preparing a zakat base working paper with the return rather than after it, linking each item to its source in the trial balance.
• Retaining documentation for deductions — particularly fixed assets and investments — in a form that remains provable years later.
• Consistency between the return and the filed financial statements, with a reconciliation schedule ready for any difference.
• Reviewing the characterisation of payments to non-residents before settlement rather than after.
• Reconciling VAT returns to the books quarterly rather than annually.

How we can help

At Almousa & Altamimi, Certified Public Accountants and Auditors we handle the side on which objections are actually decided: reading the assessment notice item by item, identifying what is worth objecting to and what is not, building the recomputation schedule and the supporting document bundle, and preparing the technical memorandum — as well as assessing the trade-off between pursuing the objection and securing the penalty waiver.

See our zakat and tax services, or contact us as soon as the assessment notice is received, not as the deadline approaches.
